Light Deflection with Torsion Effects Caused by a Spinning Cosmic String [PDF]

open access: yes, 2016
Using a new geometrical method introduced by Werner, we find the deflection angle in the weak limit approximation by a spinning cosmic string in the context of the Einstein-Cartan (EC) theory of gravity.
